In this work, Pt-Ti core-shell nanoparticles (NP) of 2 nm to 3 nm in size and 30000 u \pm 1500 u as specified single particle mass, deposited on flat silicon substrates by means of a mass-selected cluster beam source, were used for the investigation

Efficient soft X-ray spectroscopy in the laboratory is still a challenging task. Here, we report on new toroidal multilayer optics designed and applied with the laser-produced plasma (LPP) source of the Berlin Laboratory for innovative X-ray technolo

The redefinition of the kilogram will be based on Planck's constant, which can be calculated from Avogadro's constant, and hence by 'counting' the silicon atoms in a monocrystalline 28Si sphere weighing one kilogram. To reduce the influence of the su
